Abstract
Autopsy records of estrogen-treated men, castrated women, and women with breast carcinoma were analyzed with reference to the degree of atherosclerotic disease. Findings were then compared with those in similar groups of men and women whose estrogen supply was considered normal. Results obtained suggest: (1) that the male treated with estrogen has less atherosclerosis than the normal male; (2) that the oophorectomized female has an incidence of severe atherosclerosis approaching that of the male; and (3) that the hyperestrogenic female with breast carcinoma has less atherosclerosis than the normal female.
